"A high-output commercial unit hobbled by a tiny tank unless permanently plumbed in."
The 'up to 200 pints per day' output is a theoretical maximum that you can only achieve by permanently connecting the unit to a water source. Running from its built-in 1-gallon tank provides less than an hour of runtime at that rate.
This is for a user with a specific, non-residential need, like a greenhouse or grow tent operator, who requires massive humidity output and is capable of plumbing it directly to a water line. It's a brute-force tool for humidity, not a refined home appliance.
Anyone seeking a humidifier for a home living area or bedroom should avoid this. The combination of mandatory plumbing for useful output, high operating noise, and the white dust inherent to ultrasonic designs makes it a poor fit for residential use.
